DESCRIPTION

       Usage: ndselect -h|--help|-v|--version   or

       ndselect  [-b N][-e N][-s N][-F N][-L N][-I N][-S IFS][-D DELIMS][-O OSEP][-x][-l PATH][-o
       PATH] [FILE]

       Print to standard output a subset of lines and fields from a given file.

       The argument after the options is the name of the file to read from.  The complete path of
       the  file  should  be  given,  a  directory  name  is  not  accepted.  If no input file is
       specified, the program reads from the standard input.

       Exit status: 0 in case of normal termination, -1 (255) in case of error

       -b, --beginning, --start=N

       -e, --end=N

              Set  to  N the number of the last line that can be printed (The default behavior is

       -s, --step=N

       -L, --last-field=N

              Set to N the number of the last field that can be printed (The default behavior  is
              to arrive till to the end of every line)

       -I, --increment=N

              Set to N the increment to use when selecting the fields to print (The default value
